“…The volatile organic compounds from the partially burnt and unburnt materials were extracted and analysed using GC-MS. It has been reported [1,29] that cotton cloth gives rise to a number of interfering peaks, however in this study when cotton material was analysed the main background interference detected was toluene. This is most probably because the pretreatment processes of cloth are done differently locally.…”

Petrol is one of the most commonly used liquid accelerants in arson cases. It is identified by the presence of an abundance of aromatic compounds whose peaks cluster in specific patterns. The positive identification of these target compounds suggests the presence of the petrol in the debris. This information can assist a fire investigator in determining the cause of the fire, including whether or not arson is suspected. The current research aims at studying the legitimate background products in fire debris, including their identification and characterisation. A range of substrates commonly encountered at fire scenes in Mauritius were analysed in the presence and absence of petrol using the passive headspace absorption method. In unburnt samples, a number of interfering products were identified and some of the hydrocarbons liberated were those commonly found in petrol. When comparing the results of the burnt with the unburnt samples, it was found that only a small proportion of the volatiles detected in the burnt items were due to pyrolytic products and the rest were attributed to residues originally present in the unburnt items. Samples analysed in the presence of petrol, revealed that the concentration of these interfering products were below the detection limit for the accelerant and thus did not cause misinterpretation of the data.

“…In this study, they were able to show the sensitivity PDMS‐SPME fiber allowed for the detection as low as 200 μL of each accelerant . Several studies were carried out to assess the transfer and persistence of petrol on similar materials (carpets, clothing, and shoes) using either DFLEX or ACS . In the studies, hydrocarbons were recovered at levels of 100–200 μL, indicating that these methods were more efficient than those proposed by Aqel .…”

Identification of ignitable liquids from fire debris is such a major part of an arson investigation that much time and effort has gone into advancing sample preparation techniques to capture complicated and unexpected hydrocarbon compounds. Advancements in sample preparation have been made in order to account for biodegradation of commonly used accelerants, rarely encountered compounds, such as vegetable oils, biodiesel, and alcohols. Improvements have also been made to manage interference from the sample matrix, particularly with regards to new materials. This paper is a review of the sample preparation techniques that are foundational to fire debris analysis as well as recent advances. Also explored are modifications to the traditional sample preparation methods to accommodate the analysis of environmental samples (soil and water), and the presence of vegetable oils and biofuels on the fire scene.
